STORAGE
To ensure maximum stability and maintain optimum resin properties, resins should be stored in the original closed container
at temperature below 24°C/75°F and away from heat ignition sources and sunlight. Resin should be warmed to at least
18°C/65°F prior to use in order to assure proper curing and handling. All storage areas and containers should conform to local
fire and building codes. Copper or copper containing alloys should be avoided as containers. Store separate from oxidizing
materials, peroxides and metal salts. Keep containers closed when not in use. Inventory levels should be kept to a reasonable
minimum with first-in, first-out stock rotation.
Additional information on handling and storing unsaturated polyesters is available in Reichhold’s application bulletin “Bulk
Storage and Handling of Unsaturated Polyester Resins.” For information on other Reichhold resins, additives or initiators,
contact your sales representative or authorized Reichhold distributor.
SHELF LIFE
Shelf life is 3 months from date of shipment. Minimum shelf life performance refers to product in the original, unopened
container.
STANDARD PACKAGE

DIRECTLY MIXING ANY ORGANIC PEROXIDE WITH A METAL SOAP, AMINE, OR OTHER POLYMERIZATION
ACCELERATOR OR PROMOTER WILL RESULT IN VIOLENT DECOMPOSTION. WHEN ADDING ORGANIC PEROXIDES
TO A RESIN SOLUTION, PROMPTLY AND THOROUGHLY MIX THE RESULTING PRODUCT. NEVER ADD ORGANIC
PEROXIDES TO A HOT DILUENT OR PROCESS. PREVENT CONTAMINATION WITH FOREIGN MATERIALS, INCLUDING
WITHOUT LIMITATION, ACCELERATORS (SUCH AS DIMETHYL, ANILINE, OTHER AMINES OR COBALT COMPOUNDS),
HEAVY-METAL OXIDES OR SALTS (PARTICULARLY THOSE OF COBALT, IRON AND COPPER), STRONG ACIDS AND
SANDING DUSTS. USE CLEAN CONTAINERS MADE OF GLASS, POLYPROPYLENE, TEFLON, POLYETHYLENE, OR
CERAMIC TO PREVENT CONTAMINATION OF ORGANIC PEROXIDES DURING ITS HANDLING.
